Hangar doors have more than one type, including structures that can vary according to the area to be applied. • Folding aircraft hangar door • Motorized sliding hangar doors with each wing • Telescopic hangar doors are some of them. Hangar doors have a very large area as a place of use; They are designed to provide both dust and air insulation from the outside. This area can sometimes even be a facade of a building. Therefore, it is possible to choose the material that can adapt to the building facade as the hangar door closing panel. Hangar doors require perfection and high engineering education with both safety and static calculations. The key to being in service to the aviation industry, where the highest standards and zero errors are demanded, is to aim for perfection... to safely open and close a very large opening that will allow entry and exit of a very valuable and sensitive machine such as a madoors hangar door, aircraft hangar door, helicopter. It is a movable structure. In such a structure, very important engineering problems must have been solved. Doors that do not open and close in case of power cut or in snow, ice, storm, fall on the plane in storm, make the plane jump while passing over the rails, electrical cables hanging from here and there, and which are not maintained and repaired in a timely manner, carry a great risk. Small negligence can be the cause of great loss of life and property. Automatic hangar doors are manufactured according to the details developed by each company in order to provide certain technical features and safety elements, just like elevators. Madoors system hangar door doors are manufactured in the factory as modular according to the door materials project and shipped to the workplace. Cutting, drilling, boiling operations are not done in the workplace. Steel parts are manufactured from galvanized sheet or dipped galvanized. Visible surfaces are primed after chemical surface treatment and painted with UV resistant enamel exterior paint. The steel construction forming the wing body is manufactured from bent sheet profiles in the form of a modular frame. Wing panels are securely mounted inside this frame by clamping them with special clip profiles. The assembly process consists of attaching the ready parts to each other and testing the system after it is placed on the rail, and it takes a very short time compared to other known assembly applications. Our motorized hangar door productions are guaranteed for 2 years.
